Answer : B
First year : 25750 x 80% = 20600
Second year : 20600 x 80% = 16480
Third year : 16480 x 80% = 13184
Fourth year : 13184 x 80% = 10547.2
Fifth year : 10547.2 x 80% = 8437.76

Answer: Choice C</h3>
Work Shown:

In the third step, I used the rule that
. You subtract the exponents when dividing exponents of the same base.
After that, I used the rule
which is the same as saying
to end up with choice C as the answer.
Answer:
108 cubic units
Step-by-step explanation:
V = 4 cubic units
v = (1/3)³ = 1/27 cubic units
V/v = 4/(1/27) = 4/1 x 27/1 = 108 cubic units
Answers:

where 'a' cannot be zero.
=========================================================
Explanation:
The vertex is (h,k)
The x coordinate of the vertex is h which is found through this formula

For example, if we had the quadratic
, then we'll plug in a = 3 and b = -6 to get: 
------------
To find the value of k, we plug that h value into the original standard form of the quadratic and simplify.


It's interesting how we end up with the numerator of
which is similar to
found under the square root in the quadratic formula. There are other ways to express that formula above. We need
to avoid dividing by zero. The values of b and c are allowed to be zero.
Answer:
-6
Step-by-step explanation:
(2(4)+4) - (3(4)+6) = 12-18 = -6.
